Notes about the OMB file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The OMB file type is primarily associated with 'Omnibus' by Alfega Technologies, Inc.. An Omnibus file is a single, compressed and/or encrypted file linked to a Web server. Each Omnibus file on your computer is associated with a single (parent) Web server that has full access to the contents of the Omnibus file (but nothing else on your PC). In a way, you can think of an Omnibus file as an extension of the parent Web server, able to serve Web pages even in the absence of an Internet connection. An Omnibus file is like having a Web server inside of a file. You navigate the contents of an Omnibus file just as you would the original Web site.
